Just a heads up for people looking to buy this on Steam, from what I've played so far this version is pretty busted. I played through the first four stages and in that time the game crashed three times, certain portions of the background and map sometimes had code strings floating around, and I was taken back to the map unable to use any of the controls except for escaping to the menu. Upon quitting out of the game from the menu and going back into my save file I found it was corrupted and I had lost my progress. The game also didn't allow me to delete my corrupted save.
Interested in seeing if anyone else has had similar troubles with this version of the game.
